Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, and in particular to a refractory brick raw material feeding hopper. Background Technology

[0002] The refractory brick raw material feeding hopper is a key piece of equipment in refractory brick production, mainly used for storing and transporting raw materials to the next production stage. It is typically designed with a reasonable capacity and inclination angle to ensure smooth material flow and prevent blockages. Some feeding hoppers are also equipped with weighing and control systems to precisely control the amount of raw materials fed, improving product quality and production efficiency. Its robust structure allows it to withstand harsh working environments such as high temperatures and dust. In the actual production environment of refractory bricks, the existing feeding device has a simple feeding hopper design, which can only directly feed materials. Since there is no special channel for processing refractory brick waste, a large number of unqualified refractory bricks and scrap cannot be directly put into reuse. If these wastes are not properly handled, they will occupy space and waste resources. Moreover, additional waste processing requires manpower and equipment, increasing costs and affecting production efficiency and economic benefits. Therefore, this utility model proposes a refractory brick raw material feeding hopper to solve the above problems. Summary of the Invention

[0003] To address the aforementioned problems, this utility model proposes a refractory brick raw material feeding hopper to solve the problem that in the existing technology, materials can only be fed directly, and because there is no dedicated processing channel for refractory brick waste, a large amount of substandard refractory bricks and scrap cannot be directly put into reuse.

[0015] The refractory brick raw material feeding hopper conveys refractory brick raw materials into the interior of the housing 1 through the main feed inlet 2. The refractory brick raw materials pass through the bottom of the side pipe 4 and are concentrated and conveyed into the feed pipe 5. The refractory brick raw materials are sent into the crusher and crushed into powder through the feed pipe 5. The side cover 6 is removed from the top of the feed inlet. Unqualified refractory bricks are easy to break. The broken refractory brick fragments are put into the interior of the side pipe 4 through the side cover 6. The refractory brick fragments and the refractory brick raw materials enter the crusher together through the feed pipe 5. This is used to recycle unqualified refractory bricks. The unqualified refractory bricks are also manufactured according to the specified ratio. After being crushed, they are added to the raw material powder without affecting the total ratio of the raw materials or interfering with the firing and forming of the refractory bricks.

[0016] according to Figure 2 , 3 As shown in Figure 4, this embodiment 2 proposes a refractory brick raw material feeding hopper, including a box body 1, a main feed inlet 2, and a guide hopper 3. The top of the box body 1 is connected to the main feed inlet 2, and the bottom of the box body 1 is fixedly connected to the guide hopper 3. The refractory brick raw material is conveyed into the interior of the box body 1 through the main feed inlet 2. The refractory brick raw material is concentrated and conveyed into the interior of the feed pipe 5. The refractory brick raw material is sent into the crusher to be crushed into powder through the feed pipe 5. The refractory brick fragments and the refractory brick raw material enter the crusher together through the feed pipe 5 for the recycling of unqualified refractory bricks. The unqualified refractory bricks are also manufactured according to the specified ratio. After being crushed, they are added to the raw material powder, which will not affect the total ratio of the raw materials and will not interfere with the firing and forming of refractory bricks.

[0017] The bottom of the guide hopper 3 is fixedly connected to a bottom hopper 7, and the bottom of the bottom hopper 7 is connected to a discharge pipe 8. A feeding pipe 9 is connected to one side of the bottom hopper 7. An automatic feeding mechanism is provided on the feeding pipe 9. The automatic feeding mechanism includes a spiral blade 10, a rotary motor 11, and a rotary shaft 12. The rotary motor 11 is fixedly installed on one side of the feeding pipe 9. The output end of the rotary motor 11 is connected to the rotary shaft 12. One end of the rotary shaft 12 is connected to the spiral blade 10 through a connecting mechanism. The unqualified refractory brick fragments are poured into the inside of the feeding pipe 9. The rotary motor 11 can drive the spiral blade 10 to rotate at a constant speed inside the feeding pipe 9.

The refractory brick fragments and the refractory brick raw materials enter the crusher together through the discharge pipe 5 for the recycling of unqualified refractory bricks. The spiral blade 10 can easily transport the refractory brick fragments, avoiding the blockage problem caused by the refractory brick fragments getting stuck on the central shaft.

[0018] The connecting mechanism includes a connecting shaft 13, a connecting plate 14, a connecting hole 15, and a connecting bolt 16. One end of the spiral blade 10 is fixedly connected to the connecting shaft 13. Both the connecting shaft 13 and the rotating shaft 12 are fixedly connected to one end of the connecting plate 14. Multiple connecting holes 15 are arranged in a ring inside the connecting plate 14. Connecting bolts 16 are inserted into the connecting holes 15, and nuts are symmetrically threaded onto both ends of the connecting bolts 16. The two connecting plates 14 have slots 18 inside, and a locking block 17 is provided between the two connecting plates 14. The outer wall of the locking block 17 engages with the inner wall of the slot 18. When connecting the spiral blade 10, one end of the locking block 17 is first inserted into the slot 18 at the center of the connecting plate 14 connected to the connecting shaft 13. Then, the locking block 17 and the connecting shaft 13 rotate together. The rotating shaft 12 moves, inserting the other end of the locking block 17 into the slot 18 at the center of the connecting plate 14 connected to the rotating shaft 12. This is the initial connection between the rotating shaft 12 and the connecting shaft 13. Then, the connecting bolt 16 is inserted into the inside of the connecting hole 15, and the nuts are tightened at both ends of the connecting bolt 16. The nuts clamp the two connecting plates 14, so that the rotating shaft 12 and the connecting shaft 13 are connected as one unit. The spiral blade 10 is installed inside the feeding pipe 9. When the spiral blade 10 is worn out, the nuts are unscrewed, the connecting bolt 16 is pulled out from the inside of the connecting hole 15, and the connecting shaft 13 together with the locking block 17 is pulled out from one end of the rotating shaft 12. A new spiral blade 10 is installed according to the above steps, so that when the spiral blade 10 is worn out and affects normal use, a new spiral blade 10 can be installed.

[0019] The top of the box 1 is equipped with a filter screen, which is composed of horizontal bars and vertical bars. The horizontal bars and vertical bars are perpendicular to each other. The filter screen can block larger foreign objects in the raw materials and also disperse the raw materials, because raw materials tend to clump together.

[0020] The refractory brick raw material feeding hopper conveys refractory brick raw materials into the interior of the housing 1 through the main feed inlet 2. The refractory brick raw materials pass through the bottom of the side pipe 4 and are concentrated and conveyed into the feed pipe 5. The refractory brick raw materials are sent into the crusher to be crushed into powder through the feed pipe 5. The side cover 6 is removed from the top of the feed inlet. Unqualified refractory bricks are easy to break. The broken refractory brick fragments are put into the interior of the side pipe 4 through the side cover 6. The refractory brick fragments and the refractory brick raw materials enter the crusher together through the feed pipe 5 for the recycling of unqualified refractory bricks.
